Validate emails with the help of the mail
gem instead of some cluncy regexp.
Aditionally validate that the domain has a MX record.
Optionally validate against a static list of disposable email services.
There are lots of other gems and libraries that validates email adresses but most of them use some cluncy regexp.
I also saw a need to be able to validate that the email address is not coming from a "disposable email" provider.
Yes, it is used in several production apps.
Add this line to your application's Gemfile:
gem "valid_email2"
And then execute:
$ bundle
Or install it yourself as:
$ gem install valid_email2
If you just want to validate that it is a valid email address:
class User < ActiveRecord::Base
validates :email, presence: true, email: true
end
To validate that the domain has a MX record:
validates :email, email: { mx: true }
To validate that the domain is not a disposable email:
validates :email, email: { disposable: true }
All together:
validates :email, email: { mx: true, disposable: true }
Note that this gem will let an empty email pass through so you will need to add
presence: true
if you require an email
address = ValidEmail2::Address.new("[email protected]")
address.valid? => true
address.disposable? => false
address.valid_mx? => true
